Patented Mar( 4, 1941 PATENT OFFICE CIGAR WRAPPING MACHINE Ernst Hermann Jhe, Dresden, Germany, as-

slgnor, by mesne assignments, to J. C. Muller N. V., Rotterdan, Netherlands Application October s, 1936, Serial No. o4,654 In Germany October 21, 1935 6 Claims.

This invention relates to cigar wrapping machines and has for its object to provide a machine in which the completed cigars may be provided with an outside bandor two without the manual handling of such cigars. In place of the cigar band, a band such as is used in certain countries known as a customs house band or a tax band, may be applied. i

The principal object of the invention is to provide a machine which is in continuous operation and which step by step leads the article to be handled from one place of operation to another automatically through the machine. .A further object is to produce a machine which runs !5 smoothly, efiiciently, and quietly with a speed commensurate with a fair and profitable production.

For this purpose, the invention embodied in the structure hereinafter to be described consists in 2 controlling the cigars and allowing none of the same to escape such control s'o that they may be passed through the machine in order that a band may be placed thereon and thereafter `subject such band to a suitable pressing action to cause 25 adhesive, if used, to firmly hold the band around the cigar. The cigar with the band thereon is then preferably conducted by being held at its ends for the next stage of operation, which may be another presser or two, or may be another station for applying a second band, until the cigar is completed, when it is ready to be .discharged from the machine.

To carry out this invention, a cigar-holding device is provided which holds the cigar atits ends by means including a sponge-rubber-insert in a rail device or holder, and which cigar-holding device is moved longitudinally of the machine to convey the cigar from its initial position to the various stages of operation to which it is subjected. 'combined with this cigar-advancing means, other means is provided which acts by means of a suction member to take out of a conveyer the wrapper or the band and place the same in position over the cigar at the proper time. In addition, mechanism is provided in order to fold the wrapper or wrap the same over the cigar filler in one case or over the wrapped filler in the other case so that in-the case of the latter the cigar is provided with two wrappers. This mechanism is characterized essentially by the fact that a swinging movement of the mem-.

ber is utilized in order to press that portion of the wrapper which overlies the sides of the cigar filter down and under the same. Rail-like holders which grip the ends of the cigars and which are parallel with each other, move toward each other to hold the cigar, and away from each other to release themselves from the cigar and have for their object to advance the cigar in the machine and then to return to their initial posi- 5 tion. A plurality. of such grlpping fingers or holders are provided longitudinally of the machine so as to advance the cigar step by step to be wrapped or pressed. Between the two apparatuses used for the folding or wrapping of the 1 wrappers over the cigar, the intervening space is used for provision of presser members to press the wrapper securely against the filler, and such arrangement permits the operation of the machine in a manner so as to provide a relatively short path for each stage of operation and in consequence an increase in working speed of the machine, and at the same time a quiet method of operation is obtained. v

A further object of the invention consists supplying the cigar fillers to the machine itself by suitable means and thereupon holding a group of cigars which are positioned foremost, excepting the end cigar. Said end cigar is then taken hold of by the gripper or cigar holders after having been released, and while this action takes place a retarding action prevents the further feeding of the cigar fillers to the machine. When the very end cigar has been released and removed the braking action is released and a friction pad which holds a group of end cigars, is raised whereby the next cigar may be fed forward to be operated upon in like manner. For this purpose, the invention consists of a machine in which there is a step-by-step forward movement of a cigar filler which is to be wrapped by first holding the same and then releasing it and then moving it into position where a wrapper is super posed, then folding the wrapper around the cigar filler, then moving 'the wrapped cigar to one or 0 more pressure devices and then, if desired, providing a second wrapper by means similar to the first wrapping means, the cigar in these various stages being moved by parallel holders supplied by suitable sponge rubber so as not to injure the cigar ends and until after the final wrapping and the cigar is discharged from the machine.

The invention will be further described, an embodiment will be shown in the annexed drawings, and the invention finally pointed out in the subjoined claims;

In the accompanying drawings- Figure 1 is vertical longitudinal section in diagrammatic view of my improved machine;

Figure 2 is a vertical cross section of the taken on line II-II oi' Fig. 1;` 4

Figure 3 is a detailed view of the end of a cigar and a. sectional view of one -of the cigar end holders;

Figure 4 'is an enlarged full showing of the device shown diagrammatically in Figure 1:. and Figure 5 is a transverse vertical section taken through the device shown in Figure 1 to the left v is an elbow lever freely pivoted upon the axis 4..

This axis or shaft 4 carries also the driving roll 5 of the conveyor belt l The free end of the elbow lever 3 is provided with a. roller 6 which presses against a cam 8 upon the shaft 9, such pressure being brought about by the spring 'i having one end fixed to some suitable part of the frame of the machine and having the other end secured to the lever 3, so as-to pull it downwards and in consequence press its roller 6 against the cam 8. The shaft 9 is driven by means of a belt or the like from the principal driving shaft !0. To the driving shaft 9, another cam i l is keyed and this cam is acted upon by a roller I3, supported on a forked shaft follower I2' to which is connected an upright governing rod !2. The upper end of the rod i2 connects by means of a stud l4 pivotally with a lever I5, which lever 15 is in turn pivoted at l6 to a block of the frame of the machine. A spring il having one end secured to the frame of the machine and the other end applied to the forked end of the rod !2, serves to press the roller l3 against its cam H. The free end of the lever |5 is provided with a friction layer 18 made of rubber or the like, which presses, upon the proper positioning of the lever IS, upon the cigar resting upon a guide table l9, after having been placed thereon by the action of the conveyor belt I. This positiom'ng of the lever !5 is brought about by the descent of the rod z. The friction layer l8 of the lever |5 rests upon the end cigars of the row fed by the conveyor, but allows the end cigar abutting the hookshaped member 2 to be entirely free.

Upon the governing rod I2 there is arranged a brake member 20 which with the lowering of lever |5 following the descent of rod l2, rests upon a. brake disc 2| secured to the shaft 9, whereby upon a suitable force of the member 20 being applied to the disc, a stopping of shaft 3 is brought about. The shaft 9 is connected by some suitable means such as a gearing with the shaft 4, and in consequence the stoppage of shaft 3 brings about the stoppage of shaft 4. In View thereof, during this time there is no forward feeding of the cigars into the machine.

Upon therotation of the shafts 9 and 4, the lever 3 with its book-shaped portion 2 descends and permits the' free end cigar abutting thereagainst to be freely moved into the machine to be there supplied with a wrapper or two, or band, if preferred.

For this purpose, reference is now made to` Fig, 2. The guide table I9 which supports the end cigar, is 'provided with slots or openings !9' and within the slots s' there are disposed two` 'at their ends, rollers 33,459 same I oppositely directed angular holders 22, -preterabiy provided with lateral openings, and with a sponge rubber flller 9l, the flller 3! being permitted to pass out of the opening 'o'f holder 22 which permits the end of the cigar t'o be very softly held, so as not to injurethe 'same in its travel and conveyance by the holders 22. These'holders 22 'are supported on levers 23 and 24, which are fastened to tlre 'axes 25' and 26 which axes are journaled in a carrier 21. Upon axis 25 is fixed a lever 28 and upon the axis 26 is fixed a lever 29.

These levers 23 and 23 are connected by a lever 30, which is suitably adjustable by any weilknown means, not shown. Upon the axis' 25 is secured an additional lever 3l,. "connected at its free end to a governing rod 32. The rod 32 has a forked end 32' which surrounds' the shaft o and is provided with a roller 33, which cooperates with a cam 34 fixed to the shaft !0. 'A spring 35 fixed at one end to a suitable part of the frame of the machine and at its other end to the rod 32, or on a stud thereof, serves to press the roller 33 against cam 34. The rotation of cam 34 moves rod 32 up or down and the forked end 32' of rod 32 is so arranged that it permits such action.

carrier '21 is movable upon horizontal and par- ,allel rods 36, which are m`ounted ina movable arin 31. Upon arm 31 which is used as a shifter, there isa stud 33 which is surrounded by the forked end 33' of a lever 39. Lever 39 is rotatably journaled at 40 to the frame of the machine and coacts by a roller 4| with a cam 42, the roller' being supported on the 'lever 39. When the cigar holders 22 are spread apart by the action'of the cam 34 Operating through the roller 33 and the rod 32, the carrier 21 which supports the holders 22 is moved longitudinally of the machine by the cam 42 which acts through the roller 4! and the rod 33. This action of the cigar holders 22 produces the step-by-step advancement' of cigars through the banding machine in a manner which i is apparent.

By this coaction of parts the end cigar is then gripped at its ends and carried into the machine itself, until it is released from the holders 22.

Referring again to Fig. 1, it will be seen that two wrapper folding members, generally designated by A and B are shown, above and beyond the table i. Each of these devices consists of two arms 43 which by means of a stud 44 are connected with the levers 45 and 46. These levers 45 and 46 are seated at their other ends upon a common axis 41. A lever 55 is connected at one end with the lever 45, and at the other end with a commonshift rod 56. At one end of the shift rod 56 there is connected at 51 a lever 58, which is journaled at 59' in a bearing on the frame of the machine. The lowermost end of the lever 58 is provided with a roller 60, which' cooperates with a rotating cam- 6i fixed to the shaft 65. The movement of the' rod 56 in the direction of the arrow causes the'lever 55 to be moved from full to dotted lines",` and in consequence the movement of levers 45 and 43.

On the lower ends of the levers 43, folding fingers 48 are adjustably fastened which carry 49. Below the lower ends of the levers 43 is placed a band 50, the-ends of which have secured thereto ends of springs 5| which have their other ends secured to studs 5I' on the levers 43. Upon each of the levers 43 is also joumaled a roller 52, which cooperates with a cam 53 journaled in turn upon the axis levers 62 are connected with each other by rod 63. The end of the rod 83 is connected at 64 to the lever 58. Lever 58 is pivoted at 58 'and is operated by having its lowermost end cooperate with a cam 6l Secured to the shaft 65. When the rod 63 is moved by the lever 58 in the direction of the arrow each lever 62 is moved from its full line position to its dotted line position. Thereby lever 46 moves lever 43 downwardiy. As rod 56 when moved in the direction of its arrow, moves lever 55 from full line position to dotted line position, lever 45 and hence lever 43 were lowered.

The shaft 65 has two further cams 12 and 13 against which rollers operate, which rollers are on the lower ends of rods 10 and 1l each pivoted in the journal 59, and the upper ends of these rods are connected at 68 and 69 with the ends of horizontal Shift rods 66, 61, which have their other ends secured to lower parts cams 53. At the proper time these Shift rods 66 and 61 operate the cams 53 in opposite direction to each other. This operation of the cams 53 against the rollers 52, serves to move the members 48 on the lower part of the levers 43 outwardly away from each other.

Each wrapper device A and B has cooperatively related thereto, a container 14 which holds wrappers of the proper size one on top of the other. A side view of this structure is shown in Fig. 2. The container 14 is open at its bottom save for a few holding tabs. The bottom is open to permit a suction member 15 to act upon the lowermost strip. The suction member 15 seats upon a two-armed lever 16 which at 11 is journaled to a two-armed lever 18. The lever 18 is rotatably journaled in the frame of the machine by means of stud 19. On the free end of the lever 18 there is applied a roller which engages a curved cam slot 8I, upon the drum 82 Secured to the shaft n.

A guide rod 84 is connected at 83 to the free end of the lever 16, and the other end of the guide rod 84 is connected at 85 to the lever arm 86. This lever arm 86 is freely movable or rotatable on the shaft or stud 19 and is connected with a lever 81 which has a roller 88 at its free end. Roller 88 operates upon a cam 89 secured to the shaft o. A spring 80 Secured at one end'to the lever ,84 and at its other end to the lever 18, as shown, serves to press the roller 88 to the cam curve 89. By the roller Operating in the curved slot or cam 8| of the drum 82, lever 18 is moved from its full line position to its dotted line position, as shown in Fig. 2, and the suction member 15 with its wrapper held thereon is thereby moved over to the cigar held between the holders 22, after the cigar has been moved inwardly of the machine. The cams 42, 34, 8! and 88 are arranged to act in proper timing in respect to the object sought to be accomplished.

The operation of the device is as follows:

As soon as the cigar which is innermost of the row of cigars lying side by side on the conveyer I, abuts against the hook-shaped end 2 of the lever 3 (Fig. 1), the cam ll causes the friction layer |8 of the lever |5 to press upon the next three cigars, and at the same time the conveyer belt is brought to a standstill by means of the braking devices 20 and 2I. Thereupon, the cam 34 moves the levers 23, 24 in'opposite directions, whereby holders 22 close in upon themselves and enclose the innermost cigar which is free from the friction layer 18. At the same time, lever 3 is moved by means of cam 8 in such a way that the hook-shaped end 2 passes below the surface of the platform or runway l9. During the time that the cigar is held by ,the holders 22, the carrier -21 which is formed as a shifter, receives from cam 42 a forward movement into the machine, and this is to the extent until the cigar held by the holders 22 is brought to the position shown by :c in Fig. 1. During this shifting of the carrier 22, the suction member 15 has taken from the conveyer 14 a wrapper and has placed it upon the cigar in its position :I: (Fig. 4), as there shown. The cigars in Fig. 1 are shown as Squares. Before the suctionmember is guided back again to its starting position, the rods 58, 56, and 63 are operated by the cam 6l, and the levers 43 are lowered in such a manner that the folding fingers 48 place themselves upon the cigar at the same time, the band 50 presses the wrapper upon the cigar and holds it tight in that position, while the suction member returns to its initial position to take on another wrapper. Of course, instead of a wrapper, a cigar band or in some countries, a custom house or tax band may be applied. By the further lowering of the levers 43 downwardly the ends of the wrapper beyond the cigar 'are pressed downwardly by means of the folding ngers 48. If the ends of the wrapper are desired to be provided with adhesive, this may be done by means well known. After the folding fingers have crossed the underside of the cigar, the rod 66 is moved by means of the lever 10 towards the right in the sense of Fig. 1. Thereby results such a movement of the left governing cam 53, that the finger on the left hand governing lever 43 is moved towards the right, and thereby moves the corresponding downwardly extending tab of the wrapper around the cigar. Immediately thereafter the rod 61 is moved by lever 11 in such a way, that the other end of the wrapper is moved around the cigar and upon the first applied tab of the wrapper. As soon as the wrapper is thus wrapped around the cigar by means of the folding fingers 48, and with one part of the wrapper over the other, a presser 92 comes into action to press the superposed parts together. Pre'ferably this presser 92 has a rubber layer.

It is to be noted that as soon as the ngers 48, 48 respectively, the band 50, contact with the wrapper on the cigar whereby the cigar is pressed upon the guide runway or conveyer !9, the levers 23, 24 receive such movement that they are moved away from each other, thereby the ends of the cigar are freed from the holder 22 or the sponge rubber 9! therein. Thereupon the carrier 21 is returned to its initial position by the cam 42 and is then made ready to grip another cigar and move i-t forwardly. As soon as carrier 21 reaches this initial position, levers 23 and 24 are again moved towards each other as before described. At the same time the cigar with its wrapper at .7: is gripped by holders 22 with the rubber 9| thus causing the overlapped ends of the band or wrapper to become firmly attached together. It is understood that some common adhesive is applied to these ends and this pressure serves to bind the"adhesive joint. Before the carrier 21 is placed into operation anew by means of the cam 42, whereby again the step by step displacement of the holders 22 towards the right in the sense of Fig. 1 results, the lever 3 is position u, whilethe cigar which at the same time abuts against end 2 is moved to the position repeats itself tor this third cigar. But the first treated or wr'apped cigar is brought rrom position y to position y' where two press members 93 grip the cigar' 'over its wrapper again andpress it. Thereupon, the separation-of the holders 22 again takes place. The cigar then is moved bythe holders 22 rrom the position u' to the position y" and again it is pressed by the press members `93. These three press members 93 are Joined together by a common mechanism so as to operate in unison against diflerent cigars in various stages of completion in -respect to their wrappers.

It is clear that the cigars by every tour of the machine, are advanced one step further, whereby* the cigar before the hook-shaped part 2 is step by step advanced and surrounded in its course of movement by a wrapper through the action of device A.

, From the position of y", the'cigar reaches the position z, and is within the zone of operation of device B. Here a pneumaticsuction member 1 4 having a wrapper contacting end 15. draws out of the container another kind of wrapper :and by the operation of device B, this wrapper is applied to the cigar having already one wrapper applied thereto. Finally, the cigar is deposited complete in the row 94. v i
